convert_request_date(DateString) -> ErlDate|bad_date

convert_request_date/1 converts DateString to
the Erlang date format. DateString must be in one of the three
date formats that is defined in the RFC 2616.

create_etag(FileInfo) -> Etag

FileInfo = file_info()

Etag = string()

create_etag/1 calculates the Etag for a file, from its
size and time for last modification. fileinfo is a record defined
in kernel/include/file.hrl

decode_hex(HexValue) -> DecValue

HexValue = DecValue = string()

Converts the hexadecimal value HexValue into its
decimal equivalent (DecValue).

day(NthDayOfWeek) -> DayOfWeek

NthDayOfWeek = 1-7

DayOfWeek = string()

day/1 converts the day of the week
(NthDayOfWeek) as an integer (1-7) to an abbreviated
string, that is:

1 = "Mon", 2 = "Tue", ..., 7 = "Sat".

flatlength(NestedList) -> Size

NestedList = list()

Size = integer()

flatlength/1 computes the size of the possibly nested
list NestedList. Which may contain binaries.

hexlist_to_integer(HexString) -> Number

Number = integer()

HexString = string()

hexlist_to_integer Convert the Hexadecimal value of
HexString to an integer.

integer_to_hexlist(Number) -> HexString

Number = integer()

HexString = string()

integer_to_hexlist/1 Returns a string that represents
the Number in a Hexadecimal form.

lookup(ETSTable,Key) -> Result

lookup(ETSTable,Key,Undefined) -> Result

ETSTable = ets_table()

Key = term()

Result = term() | undefined | Undefined

Undefined = term()

lookup extracts {Key,Value} tuples from
ETSTable and returns the Value associated
with Key. If ETSTable is of type bag
only the first Value associated with Key is
returned. lookup/2 returns undefined and
lookup/3 returns Undefined if no Value
is found.

lookup_mime(ConfigDB,Suffix)

lookup_mime(ConfigDB,Suffix,Undefined) -> MimeType

ConfigDB = ets_table()

Suffix = string()

MimeType = string() | undefined | Undefined

Undefined = term()

lookup_mime returns the mime type associated with a
specific file suffix as specified in the mime.types
file (located in the
config directory).

lookup_mime_default(ConfigDB,Suffix)

lookup_mime_default(ConfigDB,Suffix,Undefined) -> MimeType

ConfigDB = ets_table()

Suffix = string()

MimeType = string() | undefined | Undefined

Undefined = term()

lookup_mime_default returns the mime type associated
with a specific file suffix as specified in the
mime.types file (located in the
config directory).
If no appropriate association can be found
the value of DefaultType is
returned.

reason_phrase returns the Description of an
HTTP 1.1 StatusCode, for example 200 is "OK" and 201
is "Created". Read RFC 2616 for further information.

rfc1123_date() -> RFC1123Date

rfc1123_date({{YYYY,MM,DD},{Hour,Min,Sec}}}) -> RFC1123Date

YYYY = MM = DD = Hour = Min =Sec = integer()

RFC1123Date = string()

rfc1123_date/0 returns the current date in RFC 1123
format. rfc_date/1 converts the date in the Erlang format
to the RFC 1123 date format.

split(String,RegExp,N) -> SplitRes

String = RegExp = string()

SplitRes = {ok, FieldList} | {error, errordesc()}

Fieldlist = [string()]

N = integer

split/3 splits the String in N chunks
using the RegExp. split/3 is is equivalent to
regexp:split/2 with one exception, that is N
defines the number of maximum number of fields in the
FieldList.

split_script_path(RequestLine) -> Splitted

RequestLine = string()

Splitted = not_a_script | {Path, PathInfo, QueryString}

Path = QueryString = PathInfo = string()

split_script_path/1 is equivalent to
split_path/1 with one exception. If the longest
possible path is not a regular, accessible and executable
file not_a_script is returned.

split_path(RequestLine) -> {Path,QueryStringOrPathInfo}

RequestLine = Path = QueryStringOrPathInfo = string()

split_path/1 splits the RequestLine in a file
reference (Path) and a QueryString or a
PathInfo string as specified in RFC 2616. A
QueryString is isolated from the Path with a
question mark (?) and PathInfo with a slash
(/). In the case of a QueryString, everything before
the ? is a Path and everything after a
QueryString. In the case of a PathInfo the
RequestLine is scanned from left-to-right on the hunt
for longest possible Path being a file or a
directory. Everything after the longest possible
Path, isolated with a /, is regarded as
PathInfo. The resulting Path is decoded using
decode_hex/1 before delivery.

strip(String) -> Stripped

String = Stripped = string()

strip/1 removes any leading or trailing linear white
space from the string. Linear white space should be read as
horizontal tab or space.

suffix(FileName) -> Suffix

FileName = Suffix = string()

suffix/1 is equivalent to
filename:extension/1 with one exception, that is
Suffix is returned without a leading dot (.).
